Patent FR-2290617-A1 (FR)
Title: Low pressure diaphragm valve for town gas - has two diaphragms forming three chambers fitted with manual override system
IPC: F16K17/20
Filed: 1974-11-08
Abstract: The lower part (1) of the valve has a central inlet (4) and a side outlet (6). On this is fixed a ring (2), a diaphragm (7) being sealed between them. A similar diaphragm (8) is sealed between the ring (2) and the top cover (3). A valve plug (11) passes through the both diaphragms, its lower end (12) forming a seal (6) for the gas inlet. An axial hole (18) permits gas pressure to enter the top chamber, this being assisted by a coil spring (19). The middle chamber is open to atmospheric pressure and contains a lever fork (20, 25, 26) actuated manually from outside the valve, which can selectively open or close the valve.

Title: Electrostatic coating of non conducting substrates eg glass - with resin, using silane primer to render substrate conductive
Inventor: CAHN ANDRE
IPC: B05D5/12
Filed: 1974-12-13
Abstract: Non conducting substrates e.g. glass, glazed earthenware, ligneous materials and plastics, are coated with film-forming materials by first coating the substrate with a silane, electrostatically coating with a film-forming material (I) and then heating to coalesce and opt. crosslink (I).

Title: Arginine thiazolidine-4-carboxylate - prepd. e.g. by reacting equimolar amounts of arginine and thiazolidine-4-carboxylic acid in non-aqs. solvent
IPC: C07D277/06
Filed: 1975-03-28
Abstract: Arginine thiazolidine-4-carboxylate of formula (I) is a new cpd.: it may be prepd. by reacting an equimolar suspension of arginine and thiazolidine-4-carboxylic acid in a non-aq. solvent at 20-70 degrees C and isolating the prodt. in a conventional manner, or by prepg. an equimolar aw. soln. of arginine and thiazolidine-4-carboxylic acid and isolating the resulting prodt. in a conventional manner. (I) has hepatoprotectant activity. Thiazolidine-4-carboxylic acid is converted by thiazolidinecarboxylic acid dehydrogenase into N-formylcysteine which in turn is hydrolysed to cysteine. (I) salt has a hepatoprotectant effect which is greater than that expected from the known effects of its components, and (I) has the advantage of good water-solubility, so that it may be administered orally or parenterally.
Patent FR-2306351-A1 (FR)
Title: Progressive electro-hydraulic drive - has distributor with changeover device alternately exciting electrical distributor coils
IPC: F15B21/08
Filed: 1975-04-03
Abstract: The progressive electro-hydraulic drive alternately supplies the two control chambers of a hydraulic distributor by means of an electrical distributor connecting them alternately to a source of fluid under pressure. Each distributor has an electric current changeover device alternately exciting the electrical distributor actuation coils. A pressure limitation device connected in parallel to the supply of fluid under pressure restricts the pressure to a set figure, diverting part of the fluid back to a reservoir. A continuous adjustment device regulates the excitation current of the coil actuating the limiting device between nil and maximum, so as to set the pressure to the desired figure.

Title: Multi-tool machine for moulding expanded polystyrene - using induction heating in magnetic moulds for high thermal efficiency
IPC: B29C44/34
Filed: 1975-08-14
Abstract: Multiple mould machine is for moulding expanded polystyrene or similar materials, by using moulds made of non-magnetisable metal or alloy and employing microwave induction to heat the moulding material within the mould. The beads of moulding material may be pretreated with moisture of precoated with a paraffin to enhance the rate of heat up. The number of replicate moulds would be sufficient for other phases of the moulding cycle, viz. mould filling, mould vibration, setting, cooling and ejection, to be concurrent with whichever is the longest single phase. Machine avoids energy waste associated with processes which repeatedly heat and cool the relatively large mass of a metal mould as well as the moulding material. No ancillary steam injection, steam heating or cooling water circulation systems are involved. Machine produces mouldings with minimum unit moulding cycle times, e.g., about 10 secs. per unit for mouldings weighing about 200 g.

Title: Contactless electronic vibration detector - provides logic signal output as mechanical part moves between oscillator and receiving coils
IPC: H03K17/97
Filed: 1976-12-02
Abstract: The contactless electronic detector provides a logic output signal as a mechanical part moves between coils in an oscillator circuit to interrupt a magnetic field. The detector is independent of speed of operation. A coil (4) on a ferrite pot core (3) is coupled to an oscillator (1) and is spaced from a receiving coil (6) wound a ferrite pot core (5). The two cores are contained in arms of a plastic U-shaped support (2). Receiving coil output is rectified (9) and capacitor (10) smoothed to provide a logic output (11, 12). A mechanical copper of aluminium blade (8) moving in an air gap between the coils causes the output voltage to fall to zero logic level.

Title: Ball valve for use with flammable liquids or vapours - has springs pressing on ball to conduct static electricity to earth
IPC: F16K5/06
Filed: 1977-07-21
Abstract: A ball valve for use with flammable liquids and vapours has a metal ball (4) with a diametral hole (5) and sits on a seat (6) of plastic. Because the seat material is electrically insulating there is a risk of a build-up of static electricity which could cause a spark which, in turn, could cause an explosion. To eliminate this danger two springs (15, 17) made of stainless steel are fitted. These springs provide an electrically conductive path between the ball (4) on the one hand and the body (1) and actuating lever (9) on the other hand.
